PRINTING ATTACHMENT FOR ROLL-PAPER HOLDERS.

ivPEGIFICATION formingpart of Letters Patent No. 737,822, datedSeptember 1, 1903.

Application filed April 15, 1903. Serial No. 152,702. (No model.)

To ctZZ 1072 0712, it may concern.-

Be it known that I, RICHARD E. BRUNACCI, a citizen of the United States,residing in the city and county of San Francisco, State of California,have invented an Improvement; in Printing Attachments for Roll-PaperHolders; and I hereby declare the following to be a full, clear, andexact description of the same.

My invention relates to improvements in devices that are intended to beattached to a wrapping-paper-roll support or rack and which devices areadapted to print the name or an advertisement or other matter upon thewrapping-sheet as it is unwound.

Its object is to provide a simple compact printing and advertisingmachine adapted to receive printing and inking rollers of differentdiameters and lengths and having various tension devices for adjustingit to the several rolls and to the paper-roll as the latter isdiminished.

It consists of the parts and the construction and combination of partshereinafter more fully described, having reference to the accompanyingdrawings, in which- Figure 1 is a side elevation, in partial section, ofmy invention. Fig. 2 is aplan view of same. Fig 3 is a detailprinting-roll journal and modification fink-rolljournal. Fig. at is aside view of printing-roll. Fig. 5 is a transverse section of same.

A represents an ordinary rack or holder in which is suitably supportedthe roll of paper 2, adapted to be unroiled and to have portions severedtherefrom as needed.

My attachment, which is actuated by the unwinding of the strip to betorn oif to print a label or other characters at suitable intervalsalong the length of the strip, is secured to the cross-rail of theholder above the roll by means of the clamps 3. The latter areperforated to receive a rod 4, threaded at the ends and retained inposition by means of the nuts 5.

The rod is centrally supported by a bracket 6, secured to the cross-railof the rack and having a vertical portion grooved or otherwiseconstructed to offer a secure seat to the adjacent ends of the helicalsprings S, which surround the rod between the bracket 6 and each clamp3. The other ends 9 of springs 8 aresupported on inwardly-extendingnotched projections 10 on the arms 11, which latter are'journaled inbrackets 3 and carry at their outer ends the respective printing andinkdistributing rollers 12 13.

The function of springs 8 is to press the printing-roller 12 alwaysagainst roll 2. The pressure of the roller may be increased ordiminished by slipping the ends 9 of the springs off of projections 10and giving an additional turn or two to the springs, or vice versa,according to the effect desired.

The journal-boxes on the ends of arms 11, supporting the printing rollershaft, are each formed with a hinged section 14, as in Fig. 3, normallylocked in closed position by a removable plate or keeper 15 By looseningthe latter the boxes may be opened to allow the printing-roller to bequickly removed and another put in position.

The two arms are braced intermediate of their ends by means of theremovable crosspiece 16.

This construction of separable parts is advantageous, inasmuch as itenables the same set of arms, clamps, and bracket to be used inconjunction with a variety of styles and sizes of printing-rollers, itsimply being necessary at the time of putting in a longer or shorterroller to substitute for the rod 4 and brace 16 other rods and braces ofa length corresponding to the new roller.

The ink-distributing roller 13 in Fig. 3 is shown as carried by arms 17,which extend beyond and parallel with arms 11 and are slidable in guides18 on the sides of arms 11. A spring 19 surrounds each of the arms 17between its guides 18 and has one end acting against one of said guidesand the other against a collar 20 on the arm to draw thedistributing-roller into engagement continually with the printing roller12. The latter has a portion of its surface, as 21, provided with raisedtype or other inscribing means, while the remainder of the peripheryintermediate of the segmental rings 22 at each end of the roller iscovered with cloth or other suitable absorbent material which carries asufficient quantity of ink to keep the distributing-roller 13 moist.

Roller 13 runs in the space between the rings 22, and with eachrevolution of the roller. 12 the former traverses the portion 21 tosuitably supply the type with ink. By this system of inking the typethere is little or no danger of depositing too much ink on the type atany one time, and so cause a blur in the printing.

The rings or guides 22 are coincidentin length with the cloth-coveredportion of the roller and form tracks to support that portion out ofcontact with the paper-roll, so as not to allow the paper to becomesmeared with ink. The space between the ends of each track is occupiedby the raised type portion. 21, and with each revolution of roll 12 thetype are brought into intimate contact with the paper-roll to leave thedesiredimpress.

In Fig. 3 is shown a second method of supporting the distributing-rollerin relation to the printing-roller, as where it is desired to compressthe device into as small a space as possible. Herein the shaft of roller13 is supported in removable journal-boxes 23, supported directly on thearms 11 and having spring means, as 24:, for the purpose of keeping thetwo rollers in constant contact. The rollers may be suitably incased bya removable housing 24 to protect them from dust and damage.

Having thus described my invention, what I claim, and desire to secureby Letters Patent, is

1. An adjustable roll-paper-printing device, comprising in combinationseparate clamps, a removable rod connecting said clamps, spring-actuatedarms hinged in said clamps, removable intermediate connections betweensaid arms, hinged journal-boxes carried by said arms, a printing-rollersupported in said boxes, and a spring-actuated distributing-roller.

2. The combination in a roll-paper-printing device, of clamps, aremovable rod connecting said clamps, arms hinged on said clamps, saidrod forming the hinge-pivot therefor, removable interconnecting meansfor said arms, a spring-actuated printing-roller journaled on said arms,and parallel offset spring-actuated extensions on said arms, and adistributing-roller carried by said extensions.

3. The combination with a paper-roll holder, of a printing attachmentcomprising removable clamp members, a removable rod journaled in saidmembers, a bracketsupporting the rod intermediate of said members, armspivoted to said brackets, said arms having hinged journal-boxes, aprinting-roller journaled in said boxes, an ink-distributing roller,lateral notched projections on said arms, and springs surrounding theaforesaid rod and having one end engaged by said bracket, and the othersupportedon said projections to retain the roller in contact with thepaper-roll.

4. The combination in a roll-paper-printing device, of a yieldingsupport, a printing-roller carried thereby, annular segmental guidesupon the periphery of the roller in the space unoccupied by the printingportion of the roller, whereby all but said printing portion of theroller is maintained out of contact with the surface to be printed, anda distributingroller traversing the space between said guides.

5. In a printing device, the combination with a suitable support, of aprinting-roller, annular segmental spaced guides or tracks on theperiphery of the roller in the space unoccupied by the printing portionthereof, an absorbent ink-containing covering for the rollerintermediate of said guides or tracks, and a resiliently-supporteddistributing-roller traversing said covered space and printing portion.

In witness whereof I have hereunto set my hand. I
